Um die Ernährung der wachsenden Weltbevölkerung zu sichern, ist eine Modernisierung der Landwirtschaft nötig, die sich neuer Erkenntnisse aus der Pflanzenökologie bedient. Wissenschaftler des Max-Planck-Instituts für chemische Ökologie konnten anhand von Freilandstudien an wildem Tabak nachweisen, dass dessen indirekte Abwehr von Fraßfeinden, hervorgerufen durch Abgabe von Duftstoffen zur Anlockung von Raubinsekten, die Anzahl der Schädlinge reduziert und gleichzeitig die Blütenbildung steigern kann. Biologische Schädlingsbekämpfung kann also dank natürlicher Abwehrmechanismen von Pflanzen die landwirtschaftlichen Erträge nachweislich verbessern. Die Ergebnisse erschienen in der ersten Ausgabe der neuen Fachzeitschrift eLife am 15. Oktober 2012.
